T-Test is designed to test the difference between two groups. Do you have more than two groups? Usually, the analogous test for more groups than 2 is the ANOVA test, via PROC ANOVA or PROC GLM. @Dylans15 wrote: Now that I figured out how to use proc t-test, I am running into this error- ERROR: The CLASS variable has more than two levels. Any advice? Thanks

And if you have more values the IN operator is available to avoid writing a bunch of "OR" clauses; The IN operator tests a single variable against a list of explicit values: if A1 in (11001101 1100010) then is equivalent to if (A1=11001101 or A1=1100010) then If you later need to add a third or fourth or … item just place them inside the () with the existing values. There are also some short cuts for dealing with sequential integer values: var in (3:10 27.4) would test for all the integers from 3 through 10 and the value 27.4. Character values must be inside quotes and lists do not work but this potentially saves a great many OR's in the code.

or, if you don't want to create a new table: data have; do i = 1 to 10; output; end; run; proc sql; update have set i = i*17; quit;
